Julia Garcia Gomez

Company with great knowledge of the sector, they clarified all my doubts, informing me of the most optimal system to improve the envelope of my home. Undoubtedly very professional, today there are many companies but not all of them are prepared, nor do they have professional staff. Thank you always 😊

Alma Duarte Torrejón

Very happy with the attention and quality of the acoustic fences. I recommend them.

Grupo Rocamer

They canceled an order because they didn't have it, they refunded my money and everything was correct. Although the article on their website can continue to be requested, which shocks me a bit...

Alexis Mesa

I am very grateful for the professional attention I have received at all times. The acoustic study of my cafeteria has been spectacular and has a modern design that has delighted our clients.

Grupo Emprendedores BNI Huelva & Aljarafe

Jesús González

The first time I called them was in 2018 because the pool was very poorly used and the masons who came made me botched, so I decided to call this company and it was a 100% success. The pool today is like new. 2 months ago I called them again to get an estimate for humidity in the facade that gives shade all day and they have already solved the problem. Chapo!

Marcos Alfonso

Very well explained and attended to everything

Jorge Magaz

Alberto Muñiz

From minute 1 they treated me professionally. I was asking questions because I wanted to thermally insulate my house without doing works, since I recently reformed it. I would repeat, I recommend this company 100%.

Ainhoa Souto

Very happy to be able to use the basement as an office. It was terrible with leaks and horrible humidity. It's like they changed our basement. It has been incredible. Very professional.


They responded promptly to my email inquiry. They called me on my mobile to talk about my problem and try to find a solution. Unfortunately, my case was not easy and although I did not guarantee that I would hire them, it was not a problem for their attention to be super professional and they took the time that was necessary to explain everything to me. I would recommend them without a doubt for professionalism and good customer service.

Risks of not choosing the right company to apply thermal insulation

As occurs in other construction works, there are two very dangerous underlying elements for the client:

On the one hand, the lack of professionalism, frequently derived from companies created in 24 hours and that in Numerous occasions also disappear without warning. They are companies without real technical solvency, although with an attractive advertising package, which necessarily lead to malpractice: the use of low-quality materials in many cases, and what is more important, inappropriate in others. How is this possible? It is not difficult to find applications for combustible materials in false ceilings with incandescent lights, hygroscopic materials in air chambers with moisture derived from small leaks, even materials that promote the nesting of rodents and insects, and a long etcetera.

On the other hand, the high supply derived from the above, entails a war of low prices. The problem is that, to achieve such prices, they resort to qualitative and quantitative losses. And the fact is that, as it is definitely a type of insulation that is hidden in the air chamber, they succumb to the temptation of applying amounts well below what is necessary to achieve the desired result and of materials that are not always of the contracted quality.

What can I do: We recommend that you always use approved companies with certification as specialists in the field and that you demand guarantees, as well as your detailed final works certificate.
